But the Affordable Care Act could still fail if the federal government doesn't get its act together.

Sen. Ted Cruz (R-Texas) has compared his fight to defund the Affordable Care Act to the fight against Nazi Germany. He sees it as his duty to provide "relief to the millions of people who are hurting because of Obamacare." The uninsured in his own state will tell you a different story.

Stacy Anderson, from Fort Worth, runs her own business selling sweaters online. She says she has not had health insurance for the past seven years because the sweater business is not too lucrative. "It cost more than I made some months," she says. Anderson says she was just diagnosed with skin cancer, though it is not life-threatening. "I've had it, apparently, for the entire seven years I've been uninsured," she says. "It will be nice if I can buy health insurance and get it treated."

Jeffrey Coffey is a 49-year-old from Austin who earns a living as a musician. He says has insurance, but notes that the $361 monthly premium is "way expensive" on his $22,000 salary; he says he pays more because he has asthma. Coffey says he applied for cheaper plans numerous times this year, but was turned down. "Getting rejection letters is depressing," he says. When Coffey buys insurance on the exchange, he estimates he will able to get coverage for $160 a month, a $200 savings. "But so far I haven't been able to log on to the website," he adds.

Andrew (who prefers his last name not be used) is a BFA student at Texas State University in San Marcos. He's in his mid-30s and has gone without insurance for years because it's too expensive. He has also avoided doctors for fear that he'd be diagnosed with a chronic condition, and insurance companies would "blacklist" him when he finally applied for coverage. Andrew says he no longer has to worry about that when he signs up for insurance through the exchanges this month. Andrew and his wife, a pre-K teacher, want to have a baby soon, and he says that Obamacare makes it "much more affordable for us to plan when and where we will start a family. I no longer need to worry that, god forbid, if one of us gets sick, we will be dropped from our insurance."

3.5 million uninsured Texans will finally get coverage under Obamacare. (One million more could have been covered if Gov. Rick Perry had agreed to the law's expansion of Medicaid.) Texas has the highest percentage of uninsured citizens in the country; of the 25 million people in Texas, one in four don't have health insurance coverage.

The 77 percent of Texans who already have insurance will have more comprehensive coverage than before.

Some 357,000 under 26-year-olds in Texas who would otherwise have been uninsured have gained coverage through their parents.

In 2011 and 2012, over 5 million Texans with private health plans gained free preventive service coverage.

More than 10 million Texans, including 1.6 million children, have a pre-existing health condition, such as asthma or diabetes. Because of Obamacare, insurers are not allowed to deny coverage to kids because of pre-existing conditions. Starting in 2014, insurance companies will no longer be able to charge more or deny coverage to adults with pre-existing conditions.

Because of the new law, health insurance companies now have to spend at least 80 percent of your premiumon health care costs, or provide you a refund. This means that 726,237 Texas residents with private insurance coverage will get $46,327,708 in refunds from insurance companies this year.

Obamacare bans insurance companies from imposing lifetime dollar limits on health benefits, a boon for cancer patients and other people with chronic diseases. 7,536,000 people in Texas, including 2,094,000 children, no longer have to worry about lifetime coverage limits.

Because of Obamacare, Texans with Medicare have so far saved nearly $421 million on prescription drugs. In 2012 alone, 206,304 people in the state in saved an average of $680 each.

Cruz has claimed that Obamacare is killing jobs. Some companies have blamed the health law for cuts to workers' hours, but the law is also creating jobs in Cruz' state. The federal government gave Texas $9.9 million to help enroll uninsured Americans through the exchanges, which the state will use to hire 193 workers. Obamacare also provided extra funding for doctors who practice in low-income rural and urban areas areas. There are now more than 300 of these primary care clinicians in Texas, compared with 115 in 2008.

Although Lone Star State pols have claimed that Obamacare will cause ballooning health insurance costs, the average monthly premium in the state is now lower than the national average, standing at $305. Among mid-level plans across the country, Texas has some of the cheapest; the average monthly premium for a mid-level plan for a 27-year-old is $108. (There are five tiers of health plan that can be purchased on the health exchanges, ranging from cheaper, lower quality Bronze plans to fancier Platinum plans.)

Rep. Gene Green (D-Texas), who helped draft the healthcare law, and represents the Houston area, which is home to some 1.4 million uninsured, says Obamacare is essential in Texas. "Although Houston has some of the best hospitals in the world," he said earlier this year, "The area where I grew up and now represent has one of the lowest rates of adequate health insurance for adults in the entire nation. This law has helped remedy this for communities like ours across the entire US and that's a great accomplishment."

But there's no guarantee that Obamacare will continue to benefit Texans. Perry and other GOPers in the state have done everything they can to block implementation of the law, including refusing to set up state-run health insurance exchanges. For now, Lone Star state residents have to sign up for coverage through the federal government's buggy, rickety website. If too few uninsured people sign up for health plans in a state with such a huge, hard-to-reach uninsured population, insurance prices could rise around the country and stymie the success of the law nationwide.

That's why the Obama administration and proponents in Texas are doing everything they can to get people enrolled. The administration sent Texas nearly $11 million—more than any other state—to pay navigators, the grassroots workers who help people enroll in the health plans. In Houston, city officials are modeling their efforts to enroll people on the exchanges on the emergency response systems they use in case of a hurricane or public health disaster.

But for now, the biggest thing that could help Obamacare's roll-out in Texas is an insurance exchange website that works: "I would just like to be able to sign up," Texas resident Alexandra Bonifield said on Facebook. "Fix it, please."
